It is very difficult to carry out seismic surveying. The preliminary result of the seismic prospecting indicated that only monoclines exist in the area. Drilling discovered Hetianhe gas field. After integrating non-seismic (gravity, magnetic and electromagnetic) prospecting, it was revealed that there exist two rows of structural highs, which were proved by the later seismic surveying.
